Detailed Description
The invention will be further explained with reference to the drawings.
A method for manufacturing a patch bridgewire comprises two electrode patches and a bridgewire, wherein the raw materials of the electrode patches are sheet-shaped and are formed by cutting metal plates, the bridgewire is supported by a high-temperature heating material and mainly plays a role in achieving ignition at a detonation temperature, and the material can be nickel-chromium, platinum-iridium and other materials in the prior art.
The manufacturing method comprises the following steps:
a through groove 2 or a groove is formed in the electrode patch 1; here, the through grooves and the grooves have similar functions, and the through grooves are described as an example in this patent.
As shown in fig. 1, the end of the electrode patch 1, where the bridgewire 3 is disposed, is bent toward the through groove 2 or the groove, and a projection of the bent portion 4 on the electrode patch 1 is ensured to cover the through groove 2 or the groove, and a gap capable of allowing the bridgewire 3 to be inserted is ensured between the bent portion 4 and the body of the electrode patch 1; here, the main body of the electrode patch 1 is mainly a main body portion which is bent, and thus a bent portion 5 is inevitably present, unlike a flat electrode patch made of a raw material.
Arranging the bridgewire 3 in a gap between the bent part 4 of the electrode patch 1 and the body of the electrode patch, and ensuring that the bridgewire 3 is positioned between a bent part 5 formed by bending the electrode patch 1 and the through groove 2 or the groove;
extruding and attaching the bent part 4 of the electrode patch 1 to the body of the electrode patch 1; here, the gap between the originally bent portion 4 and the body of the electrode patch 1 is flattened, thereby fixing the bridge wire 3 to some extent.
As shown in fig. 2 and 3, the bent portions 4 attached to the body of the electrode patch 1 corresponding to the through grooves 2 or the grooves are punched to fix the corresponding bent portions 4 to the body of the electrode patch 1. The metal is impacted in a mode of stamping to form a fixed locking part, the whole process is a mechanical bending process, an extruding process or an impacting process, high temperature is not involved, and the contact is firm, so that the resistance value of the whole patch bridge wire is stable, and the influence on the bridge wire 3 is small. The through grooves 2 or the grooves may be formed in an inverted trapezoidal structure for easy punching, and the through grooves 2 are different from the grooves in that the punching condition can be observed from the rear portion of the patch bridgewire by the through grooves 2, and the dents can be observed only at the bent portions 4 by the grooves, so that the through grooves 2 are the best mode. (Note that the grooves in FIGS. 2 and 3 are not through grooves 2 in FIG. 1, but are formed in a groove shape formed by the portion of the bent portion 4 that enters the through groove 2 after being impacted)
In order to prevent the stress change of the part punched in the through groove 2 due to high temperature when the patch bridge wire is welded on a control circuit, the bending part 4 and the body of the electrode patch 1 can be welded in the through groove 2 in a laser welding mode, even if welding is adopted, the electrode patch 1 is only contacted with the bridge wire 3, so that the integral resistance performance is not influenced, the welding is finished instantly, and the temperature cannot influence the bridge wire. It should be noted here that the welding position here specifically refers to the bent portion 4 and the back surface of the body of the electrode patch 1 after the punching in fig. 3, where there is a gap in contact therebetween.
If it is a groove structure, welding is performed at the bent portion 4 and the gap connected to the side of the body of the electrode patch 1 by means of laser welding, although the structure of the through groove 2 may be used.
The invention also provides a patch bridgewire, which is obtained by the method described above and is not described in detail herein.
The present invention has been described in detail with reference to the preferred embodiments. However, variations and additions to the embodiments will become apparent to those of ordinary skill in the art upon a reading of the foregoing description. It is the intention of the applicants that all such variations and additions fall within the scope of the invention as claimed.
